COUPLING TOOLS FOR. DRILLING..-

Specification forming part of Letters Patent No. 47.03 I, dated March 28, 1865.

so (ill whom zit-may concern:- Be it known that l, J om; Ronnn'r Moonn, of Brooklyn, Kings county, New York, have invented, mode, and applied to use a nc'wancl.

Improved Mode of Coupling Tools for Drilling and other Purposes; and I do declare the following to be a. full, clear, and correct description of the some, reference being bad to the accompanying drawings, making port of. this specification, and to the letters of reference marked thereon, i11 -which Figure 1 is eview or two sections of a. drill-'. ing -tool coupled byrny improved mode; Fig.

2, o. longitudinal section of'the some; Fig. 3, detached views of sections of tool and cap or collar I i g. 4;, on end View of section of tool Fig. 5, end view of cap or collar.

in the drawings like parts of the invention are indicated by the same letters oireference.

' with the shoulder a, having out upon its interior the female thread a and upon its exterior thc-malethread a.

' B is a. second section of a. shaft, auger-stem,-

bit, or any tool, provided at its bottom end with the male thread b, screwing into the femele thread a upon theinterior of the shoulder upon the section'A. This-section B is also provided with the shoulderb.

0 shows a cap or-' collar having upon its interior the Thevariousportsbeing thus constrncted,the second section B is connected tothe first section A by screwing the male threadb on the seclion B,i'nto thefemale thread a.,'uponthe section A,until the shoulder 'b" is bronghtflush against female thread 0 and theshock the. shoulder a. The cap or collar 0 is then placed over the section B, and. thefemale thread 0 is screwed into the male thread a upon the shoulder o until the shoulder c upon the interior of the cap or collar (3 beers snugly upon the shoulder b? upon the sec- .tion B.

My invention will be 'ihund particularly I valuable in coupling tools used in boring ortesia-n and oil wells. The tools at present usedinborin'g artesian and oil wells are connected or held together by simply screwing one into the other. Q

, The diihculty experienced (a. most serious one) when tools are thus coupled has been that in-process of drilling or boring the tools frequently become unscrewed and are lost,

and if not lost very much time, labor, and

expense ere expended iii-recovering them.

By the use of myinvention this difiicnlty is entirely obviated, osthe presence of tho'cop or collorprerents the tools becoming unscrewed while in use, while its cost is but little. in excess of the present mode It will he perceived that the lower section,

- B, is provided with e right-handed thread,

while the cap or collar is provided with o. lefthanded thread, so that any liability of the section to unscrew only tightens the cap or collar. While in some cases both the thr ads upon the section A, or, more definitely, upon the shoulder a ,and the section B,"1nny be right-handed threads, iuwhich caseone thread may be made finer than the other, I prefer the method herein'shown Having thus described my invention, what 3 I claim as new, and desire to secure by Letters Patent, is

The improved mode of coupling, subslun' tially as described.
